Not a direct answer to your question per se, but I would wholeheartedly recommend Frank O'Brien's "The Apollo Guidance Computer: Architecture and Operation" (ISBN 978-1-4419-0876-6).
It reads like a lead engineer walking a new hire through the codebase.

This is a great recommendation. And considering the code base is in assembly, I'll gladly welcome a walkthrough.
